Annotation:

Perspectives of using of heteropolycompounds (HPC) as catalysts in isopropanol dehydration are shown. Optimal composition and concentration of HPC on the surface is found. The catalysts provide maximal yield of diisopropyl ether (DIPE) of 21.3 %. The influence of basic parameters of the process on the activity and selectivity of the catalysts is studied. The best result is obtained at temperatures of 135−145 °С and concentration of water 2 % wt. Based on HPC catalysts were shown to possess the higher activity (up 5−10 times) as compared with industrial zeolite catalysts
